Chassis weight and roof rack?
Anyone know the rough weight of a book chassis and if it will be safe on the roof of a Scenic (all be it on a roof rack)!
Cheers,
Pat...

it says in the book 35lbs if my memory serves me correctly.
there is a pic of a guy holding it anyway, so imagine a roof rack will be more than strong enough.

Tom,
Notice that chassis is a little shiny? I'm pretty sure we concluded it's an ally one!
There's no way the chassis is that light- you can only just lift a complete steel one. Either that or Chairman Ron was working out before taking
that picture!
Pat,
I took my chassis home on OEM Peugeot 406 estate roof. It didn't have the floor in then but was mostly complete. Seemed to survive ok!
I use some 2x4 cross members at 90° degrees to the roof rack so there was a bit more to strap it too!
HTH,
James

I think you'll find that bare chassis' come out at about 65 lbs before panelling. Should be OK on a roof rack if you take it easy.

Finish the car and put the Scenic on top!!
Seriously, my chassis weighted 9 stone will all the brackets and braces, but no floor or panalling
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Kit car workshop collected a fisher fury chassis on a roof rack last month.
3 car pile up and mangled chassis was the end result.
I think though that most roof racks are strong enough to take a chassis ok.
Kind regards,
Darren

Scotlad went to look at the MK.Martin had some punter not pick up his kit. He cracked a deal with Scotlad who went to Halfords for a rack and ended
up coming back with the car on his estate. All the other bits went inside. And that was worksop to Edinburgh
Ive carried my other chassis on the minty metro!

When I picked up my Indy kit we brought that back on the roof as well as the ally floor and didn't have any problems. Tie it down nice and
securely and it doesn't seem to move about

Weight is not the concern, you need a REALY heavy frame to make the roof rail collapse...
Just run not too fast, aero drag can be much more than 70 kg..

I've often wondered about drag induced forces as I've found myself
making progress on the motorway before remembering I had this on the roof...
...doesn't seem to cause it any problems until I put two boats on top and then you can see the boats causing the rack to twist slightly at
anything over 100 (an experiment on a private road, obviously).

We hired a trailer. We got it for £0 because my dad had to sort out the electrics first. It was towed by a Volvo V70 D5.

I was wrong, the overall drag of a comon car at 90 km/h should be about 1000N.
Force x Speed = Power
Power = 25 kW
Speed = 25 m/s
Force = 25000/25 = 1000N
Only a frame won't have a big drag.
Meanwhile the frame must have completed the trip 5 or 6 times...

Just for info and for reference for anyone else asking the same question in the future, my chassis (as in the picture) weighed in at 70kg.
